Feline Life Stages

Cats are living longer these days, longer than ever before. Recently the American Association of Feline Practitioners (AAFP) and the American Animal Hospital Association (AAHA) released new guidelines for Feline Life Stages. The new Feline Life Stage Guidelines breaks the feline lifestage into six distinct stages.

Kitten – Birth to 6 months
Junior – 7 months to 2 years
Prime – 3 years to 6 years
Mature – 7 years to 10 years
Senior – 11 years to 14 years
Geriatric – 15 years and older

One thing clients are always interested in knowing is how old your cat is in human years. We have always gone by the old adage that cats age seven human years for one cat year. To go along with the new Feline Life Stage Guidelines, the AAFP and AAHA also released a new chart for your cat’s age in human years.

Fun Cat Age Facts

Cats live longer than dogs

Cats age faster when they are younger, but it slows down as they get older.
